I want to go from a size 32B to a size 32C and i just want to know how much it costs?

Pricing really varies depending on the surgeon, location, and several other factors. $8000 to $9000 would be the average in Toronto. It is important to know that the size of the implant does not affect pricing generally speaking.

The cost of your surgery will not be affected by the size of the implant that you choose. But it will be affected by the type of implant (saline, silicone gel, form stable, etc), the surgeon your choose, the anesthesia and operating facility, among other things. The costs vary considerably by geographic location and from surgeon to surgeon. 

There may be many “variables” involved. The specific surgeon's credentials/experience level (or lack thereof), the specific geographic area you are looking at, the different operations available, the location of the procedure ( quality of surgery facility), type/quality of anesthesia provider, type of breast implants… are some of the potential variables involved.  You will find some average costs of surgery listed on this website and on individual plastic surgeons' websites as well (please see attached link).
In regards to outcome of the planned procedure, more important than costs of the procedures will be careful selection of your plastic surgeon. I would suggest starting with the American Society of Plastic Surgery and/or the Aesthetic Society of Plastic Surgery to obtain a list of well experienced board-certified plastic surgeons.
Then, I would suggest you visit a few surgeons whose practices concentrate on aesthetic surgery. Ask to see lots of examples of their work and preferably speak/see patients who have had similar procedures done.
Be very careful with your decision-making. You will find, while doing your due diligence, that there are many different “specialties” who will offer their services to you; again, I strongly recommend you concentrate on surgeons certified by the American Board of Plastic Surgery.
Again, I would also suggest that you do not base your selection of plastic surgeon primarily on costs of surgery; keep in mind that revisionary surgery may be more costly in many ways.  Best wishes.
